Martín Bigio 6eea41c718 [react-packager] Avoid referring `Module` like objects in `BundlesLayout`
Summary:
The `BundlesLayout` will be used as a persistent index. As such, it would be easier to avoid having dependencies to `Module`, `Package`, `Asset`, etc. We're not using that information for now and if we happen to need to use it we could always fetch it using the `ModuleCache`.

Martín Bigio 51e1a1f6a2 [react-packager] Move async dependencies to `System.import`
Summary:
We've decided to move the syntax for asynchronously requiring async dependencies. The new syntax works better with promises and therefore withe async/await as well. The new syntax looks like this: `System.import('moduleA').then(moduleA => {...});` or if you're using async/await you could simply do:
  let moduleA = await System.import('moduleA');
  new moduleA().someFunction();

If you need to require multiple dependencies just do:
  Promise
    .all([System.import('moduleA'), System.import('moduleB')])
    .then((moduleA, moduleB) => {...})

or the equivalent using async/await

Harrison Harnisch ef7dc94907 UI CPU and memory utilization graphs in Chrome debugging mode
Summary:
Chrome debugging UI is currently only showing connection state and logs in the console, leaving room for plenty of interesting information.

I've pushed the UI (using the same convention set by FPS -- UI/JS) CPU and memory utilization data over the debug Websocket and tapped into the existing stream of JS calls that get ran in V8.

The number of JS calls in a time interval is counted for all sub calls in a batch
https://github.com/hharnisc/react-native/blob/master/packager/debugger.html#L150

The last 5 batches of JS calls are displayed in a list format.

Martín Bigio 06eb63b54d [react-packager] Introduce bundle IDs and keep track of parent/child
Summary:
Since JS doesn't have the guarantee that once a bundle is loaded it will stay in memory (and this is something we actually don't want to enforce to keep memmory usage low), we need to keep track of parent/child relationships on the packager to pass it down to native. As part of this diff, we also introduced an ID for each bundle. The ID for a child bundle is shynthetized as the bundleID of the parent module + an index which gets incremented every time a new bundle is created. For instance given this tree:

       a,b
    c       f
  d   e       g

the ID for `d` will be `bundle.0.1.2`, the one for e will be `bundle.0.1.3` and the one for `g` will be `bundle.0.5.6`. This information will be useful to figure out which bundles need to be loaded when a `require.ensure` is re-written.

Amjad Masad 54a8fe9156 [react-packger] Add a timeout on transform jobs
Summary:
There's been a case where Babel can hang indefinitely on a file parse/transform. Possibly related to https://github.com/babel/babel/issues/2211

This adds a timeout to transform jobs and throws an error informing the user of the offending file. The timeout interval defaults to 10 seconds, but can be changed via an option.

Amjad Masad 866df6d37c [react-packager] Wait for haste map before accepting any requests
Summary:
D2319999 introduced a regression where we stopped waiting for the "build haste map" step to finish before we accept any requests. This makes sure that we block on that.

Need to unbreak with this, but will follow up with a test to catch this in the future.

Amjad Masad 3555afb66d [reat-packager] Switch platform resolution based on query param
Summary:
Currently the platform selection is controlled by the blacklist. However, since we want to use the same server instance for cross-platform development, we need this to be controlled per request.

One outstanding issue, is that the DependencyGraph class wasn't designed that way and it doesn't have a per-request state. This means that with the current design race conditions is possible. If we got a request for a different platfrom while processing the previous request, we may change the outcome of the previous request.

To fix this a larger refactor is needed. I'll follow up a diff to do that.

Finally, so I don't break the universe like last time, I'll leave it up to the RN guys to update the call sites.

Amjad Masad cc01b6daf4 [react-native] Set NODE_ENV and use node-env-inline plugin
Summary:
This sets NODE_ENV based on the value of the `dev` option when bundling the apps. This would then be inlined by the node-env-inline babel plugin. And finally -- if unreachable -- will be dead-code-eliminated by uglify.

This is not used in development because we set NODE_ENV to the value of __DEV__, which can be switched via a query param. However, the plugin has minimal overhead and to avoid complexity in the transformers I just enabled it by default.

Martín Bigio fec5d8d4d4 [react-packager] Cache in which bundle is each module
Summary:
Not that at the moment a module can be present in multiple bundles, so the new API will return only one of them. In the near future we'll impose the invariant that a module can only be present in a single bundle so this API will return the exact bundle in which it is.

Amjad Masad 7664d5fb76 [react-packager] Use module objects across the codebase (rid of getPlainObject etc)
Summary:
Instead of using plain objects and having to convert to and from them we just use the `Module` class across the codebase.
This seems cleaner and can enforce the type as opposed to fuzzy objects.

Martín Bigio 8644bfd09c [react-packager] Introduce Bundler
Summary:
Introduce a Bundler capable of generating the layout of modules for a given entry point. The current algorithm is the most trivial we could come up with: (1)it puts all the sync dependencies into the same bundle and (2) each group of async  dependencies with all their dependencies into a separate bundle. For async dependencies we do this recursivelly, meaning that async dependencies could have async dependencies which will end up on separate bundles as well.

The output of of the layout is an array of bundles. Each bundle is just an array for now with the dependencies in the order the requires where processed. Using this information we should be able to generate the actual bundles by using the `/path/to/entry/point.bundle` endpoint. We might change the structure of this json in the future, for instance to account for parent/child bundles relationships.

The next step will be to improve this algorithm to avoid repeating quite a bit dependencies across bundles.

Martín Bigio ce6acf1586 [react-packager] Introduce `require.ensure`
Summary:
This is the first step to add support for splitting the JS bundle into multiple ones. This diff adds support for keeping track of the async dependencies each module has. To do so we introduce the following syntax:

  require.ensure(['dep1', 'dep2, ..., 'depN'], callback);

Where the callback function is asynchronously invoked once all the indicated modules are loaded.

Internally, the packager keeps track of every set of async dependencies a module has. So for instance if a module looks like this:
  require.ensure(['dep1'], () => {...});
  require.ensure(['dep2'], () => {...});

the `Module` object will keep track of each set of dependencies separately (because we might want to put them on separate bundles).

Amjad Masad 3f1619b158 [react-packager] Rename 'Package' to 'Bundle'
Summary:
The word Package is overloaded, it may mean npm package, or may mean a collection of bundles. Neither is what we mean. We mean `bundle`.

This renames it and modernize some of the Bundler code.

Martín Bigio 49fde903b8 [react-packager] Promote Cache to top level
Summary:
The cache is only used for JSTransformer at the moment. We're doing IO and some computation to get each module's name, whether is a haste or node module and it's dependencies. This work happens on startup so by caching this value we shouldbe able to reduce the start up time. Lets promote the Cache to the Packager level to be able to use it by any of the components of the packager. For now, on this diff we'll start using it to cache the mentioned fields.

Also we had to introduce the concept of fields in the cache as manually merging the date we had for each path is not possible as we're using promisses all around. With the new API, each field is a promise.

@amasad and I did some manual testing to measure the impact of this change and looks like it's saves 1 second when building the haste map (which represents 50% of the time). Overall this reduces 1 second of start up time which was currently about 8s on my mac book pro.

James Ide 7b1ffed4e7 [Async] Enable async/await and update UIExplorer and tests
Summary:
- Enables async/await in .babelrc and transformer.js
- Adds regenerator to package.json. Users still need to explicitly require the regenerator runtime -- this is so that you only pay for what you use.
- Update AsyncStorage examples in UIExplorer to use async/await
- Update promise tests in UIExplorer to use async/await in addition to the promise API
